Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598860, here are decompositions:

3 + 31598857 = 31598860
71 + 31598789 = 31598860
89 + 31598771 = 31598860
107 + 31598753 = 31598860
173 + 31598687 = 31598860
191 + 31598669 = 31598860
269 + 31598591 = 31598860
317 + 31598543 = 31598860

Showing the first eight; more decompositions exist.
